Speed of sound = 343 m/s
Speed of sound = (frequency)(wavelength)
Power = intensity in W/m2(Area)
area= (4pir2)
W/m2 to dB = 10dBLog(I/Io)
Sound intensity level:
Io = 1.00 x 10-12W/m2

The 95% confidence interval for the m coefficient of the actual is between 6.28 and 13.52.
The expected m coefficient is 4.32 which does not lie within the 95% confidence interval

Rotational Motion
Introduction
Until now, objects have been treated as point
particles
The point particle treatment is the correct way to
describe translational motion

Work and Energy
Introduction
Newtons Second Law leads to definitions of work
and energy
The concept of energy can be applied to individual
particles or a system of particles

Introduction
Objects have been treated as point particles
Mass is located at a single point in space
This assumption is very useful
This is the correct way to deal

Mechanics
Mechanics is one area of physics
It is concerned with the motion of objects
Two questions need to be answered to understand
mechanics
What causes motion?
